I now see that Mesa (libGL, dri, ...) is built with GCC on i386; never
noticed that before. See graphics/libGL/bsd.mesalib.mk:
# i386 triggers clang bug 19778. This happens with clang 3.4.1 and older.=
=2E if ${ARCH} =3D=3D i386
USE_GCC=3Dyes
=2E endif
The bug is described here:
http://llvm.org/bugs/show_bug.cgi?id=3D19778
I add Dimitry into the loop: Dimitry, do you have any news for this
Clang bug?
Buildling Mesa with GCC causes the usual libc++ vs. libstdc++
incompatibilty:
libGL error: dlopen /usr/local/lib/dri/r600_dri.so failed
(/usr/local/lib/dri/r600_dri.so: Undefined symbol
